By the looks of what's going to come for RHEL8 I think it already contains a suitable LLVM and clang (i.e. >= 3.9)? > As far as I know clang does promise gcc compatibility in > the sense that one can link together .o files compiled with both so I > expect the combination not to cause issues (assuming the other > compiler flags affecting binary compatibility are aligned). Right. But that's not even needed, as we just use plain old C ABI via dlsym(). Nothing needs to be linked together outside of dlsym(), so I'm not too concerned about that aspect.
